/* ==========================================================================
   Editor.js blocks + rendered post content
   --------------------------------------------------------------------------
   The project shipped the Editor.js *scripts* (assets/vendor/editorjs/, all
   UMD builds) but never the CSS — so both the editor and every published
   post rendered tables without borders, code without a monospace font and
   ASCII diagrams with broken alignment.

   This file covers both surfaces:
     • editor view  — .ce-block, .cdx-block, .tc-table, .ce-code__textarea …
     • published    — .post-content pre / code / table / blockquote / figure

   Colours come from the app theme tokens (themes.css), so dark and light
   both work without a second rule set.
